63 FOREWORD
64 1) The International Electrotechnical Commission (IEC) is a worldwide organization for st andardization comprising
65 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
66 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
67 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
68 Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
69 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
70 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
71 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
72 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
73 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
74 consensus of opinion on the relevant subjects since each technical committee has representation from all
75 interested IEC National Committees.
76 3) IEC Publications have the form of recommendations for international use and are accepted by I EC National
77 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
78 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
79 misinterpretation by any end user.
80 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
81 transparently to the maximum extent possible in their national and regional publications. Any divergence between
82 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
83 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
84 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
85 services carried out by independent certification bodies.
86 6) All users should ensure that they have the latest edition of this publication.
87 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
88 members of its technical committees and IEC National Committees for any personal injury, property damage or
89 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal f ees) and
90 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
91 Publications.
92 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
93 indispensable for the correct application of this publication.
94 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
95 rights. IEC shall not be held responsible for identifying any or all such patent rights.
96 IEC 61010-2-033 has been prepared by IEC technical committee 66: Safety of measuring,
97 control and laboratory equipment.
98 It has the status of a group safety publication in accordance with IEC Guide 104.
99 This third edition cancels and replaces the second edition published in 2019. This edition
100 constitutes a technical revision.
